BACKGROUND

Individuals, especially women but sometimes men as well, have their hair curled for events, including weddings, dances, and parties generally. Many also have their hair prepared for job interviews or even regular days at work. Typically, people go to a hair stylist when they are preparing for significant events but handle their hair themselves in preparation for events that are less significant. That being said, people would prefer to prepare hair themselves in order to reduce cost, and therefore are willing to invest in many professional tools. But many of these professional tools are designed to be held by a second person and applied to the hair of the first person. Consequently, it is often difficult for the first person to use these professional tools. What is needed is professional-grade tools that are customized, oriented, or configured to be handled by the first person.

SUMMARY

The present application describes a curling iron that can be configured for multiple positions. The curling iron has an iron portion and a handle portion. The handle portion may be connected to an electrical supply and may include an integrated circuit board, monitor display, and user control panel. The iron portion and the handle portion may be connected by means of a rotating mechanism.

The handle may be made of thermally non-conductive material such as plastic. It may comprise a first end and a second end, the second end connected to a power source, the first end engaged to the iron portion. The handle may be contoured or feature ridges configured to be held ergomically by the human hand. These ridges may be arranged so as to accomodate the hand holding the handle across multiple positions of the iron.

The iron portion may be made of thermally conductive material, such as metal or certain ceramics. The iron portion may be embedded with one or more heating elements. The heating elements may be controlled thermostatically, and connected to the electric source which provides the current used to raise the temperature of the heating elements. The current flow may be controlled by a control mechanism, which may provide a range of heating profiles or a discrete set of heating levels. The control mechanism may be diposed in and accessible from the handle.

The rotating mechanism may comprise a bar coupled to a cylinder, such that the cylinder is fitted to the bar and may rotate freely around it. The cylinder may feature an extension portion and connect to either the handle portion or the iron portion via the extension portion. The extension portion may extend orthogonally from the main axis of the cylinder, the main axis traversing the hollow. The bar may attach to the handle portion or the iron portion at the one or more ends. In one variation, the handle or iron portion may feature two extensions from the near side, each of these extensions featuring a cyndrical hollow. The bar may be rotationally engaged to the set of double hollows.

The rotating mechanism may be spring-loaded, or use a mechanism that uses tension to provide a default orientation but permits motion of a constant pressure is applied.

The rotating mechanism may be coupled to a second rotating mechanism, the second rotating mechanism operating orthogonally to the first rotating mechanism. The second rotating mechanism may feature a dual set of cylinders, one cylinder being exterior to the other with each attached to separate parts of the iron. In one variation, the rotating mechanism is coupled to a ball in joint mechanism for 360 degree or spherical movement. In yet another variation, the ball-in-joint mechanism is positioned in lieu of the rotating mechanism. In these variations, the handle can rotate angularly with respect to the iron portion as well as in line with and around a shared axis.

The cylinder and/or bar may feature radial extensions such as those found on a gear. The extensions may be female and male, respectively, and configured so as to engage with one another. The cylinder and bar may have one or more portions that are flush with respect to one another such that they may rotate without friction. There may be lateral portion that controls or adjusts the track on which the cylinder and/or bar are positioned, so as to switch between a gear and flush relationship, thereby impeding or facilitating rotation. There may also be a locking track that prevents rotation altogether.

Positions determined by the tracks may include a 180 degree configuration, 90 degree configuration, as well as other angular configurations arranged evenly between those two configurations.

The track or position of the rotating mechanism may be controlled by the user by means of the lateral portion, which may extend in the form of a button, switch, or lock. The user may also forcibly rotate the handle toward or away from the iron portion in order to control the angle. An extension portion, extending from either the handle or the iron portion, may prevent complete rotation.

Electrical wiring may traverse the rotating mechanism by extending through one or both ends of the bar and through a hole disposed on a surface of the cylinder and exposed to the hollow, or around the cylinder.
